Abstract

An airbag for a vehicle comprising an inflatable portion and lugs arranged at the periphery of the inflatable portion. The airbag is made of a one-piece-woven technology having a structure made of warp threads and weft threads. The airbag further comprises a marking for enabling a detection of an incorrect attachment of the airbag at the vehicle. The marking is realized by a coded weaving structure in at least one lug.
